I think a nicer way to solve that issue is to use Cabal's MIN_VERSION macros.
1. Add CPP to your extensions. This will cause cabal to
auto-generate a file with MIN_VERSION_<pkg> macros for each <pkg> in
build-depends.
2. GHC 6.12.* comes with template-haskell 2.4, so to test for that use:
#ifdef MIN_VERSION_template_haskell(2,4,0)
.. ghc-6.12.* code here.
#endif
This should make it more transparent to the user.

Dear list,
From ghc 7.0.1 release notes:
The Language.Haskell.TH.Quote.QuasiQuoter type has two new fields: quoteType and quoteDec.
Some of my code needs to be conditionally compiled to support both version 6 and 7, what is the recommended way to do it?
